M2 Solar Flare (R1 Minor Radio Blackout) with CME

M2 Solar Flare (R1 Minor Radio Blackout) with CME
published: Wednesday, February 11, 2015 17:05 UTC
NOAA Active Region 2282 produced a M2 (NOAA Scale R1- minor) solar flare at 09/2335 UTC (6:35 pm EST yesterday evening).
 
As is frequently the case with larger flares, this event was associated with a coronal mass ejection (CME). However, analysis and subsequent model runs of this event have determined that the trajectory of the CME is not on a Sun-Earth line.
 
As always, SWPC forecasters will be watching Region 2282 as it rotates into a favorable position to produce more CMEs that could potentially produce geo-effective events.

Hopeful Aurora watchers - standby for the chance of more activity in the coming week.
